Intentando consultar para encontrar los campos personalizados de usuario llenados

Tengo una consulta de explorador de datos en la que intento encontrar a todos los que han completado el campo personalizado de usuario 1-4, y me encantaría que solo muestre aquellos con los 4 como columnas para cada usuario, pero mis habilidades de Postgres son limitadas y no he podido resolverlo:

SELECT user_id, name, value
FROM user_custom_fields
WHERE name IN ('user_field_1','user_field_2','user_field_3','user_field_4')
    AND value IS NOT NULL
ORDER BY user_id ASC, name ASC

I’m sure there are better ways of approaching this, but this should work to give you a single row containing all of the fields for each user who has filled out at least one of your user fields.

WITH user_field_1 AS (
SELECT ucf.value,
ucf.user_id
FROM user_custom_fields ucf
WHERE ucf.name = 'user_field_1'
AND ucf.value IS NOT NULL
AND ucf.value != ''
),
user_field_2 AS (
SELECT ucf.value,
ucf.user_id
FROM user_custom_fields ucf
WHERE ucf.name = 'user_field_2'
AND ucf.value IS NOT NULL
AND ucf.value != ''
),
user_field_3 AS (
SELECT ucf.value,
ucf.user_id
FROM user_custom_fields ucf
WHERE ucf.name = 'user_field_3'
AND ucf.value IS NOT NULL
AND ucf.value != ''
),
user_field_4 AS (
SELECT ucf.value,
ucf.user_id
FROM user_custom_fields ucf
WHERE ucf.name = 'user_field_4'
AND ucf.value IS NOT NULL
AND ucf.value != ''
),
target_fields AS (
SELECT
u.id AS user_id,
uf1.value AS user_field_1,
uf2.value AS user_field_2,
uf3.value AS user_field_3,
uf4.value AS user_field_4
FROM users u
LEFT JOIN user_field_1 uf1
ON uf1.user_id = u.id
LEFT JOIN user_field_2 uf2
ON uf2.user_id = u.id
LEFT JOIN user_field_3 uf3
ON uf3.user_id = u.id
LEFT JOIN user_field_4 uf4
ON uf4.user_id = u.id
)

SELECT
*
FROM target_fields tf
WHERE tf.user_field_1 IS NOT NULL
OR tf.user_field_2 IS NOT NULL
OR tf.user_field_3 IS NOT NULL
OR tf.user_field_4 IS NOT NULL
ORDER BY tf.user_id

If there is a better way I am so ok with trying/doing it! I’ll give this a shot though.

By ‘better’ I mean more elegant and more efficient. This should give you the results that you are looking for. I was stuck for a while on how to get the results in a single row for each user. If that isn’t a requirement, the query could be simplified a lot.
